Toa ll whom it may concern:

Be it known that I, WALLACE APPLETON -BEATTY, a citizen of the United States, re-

siding at New York city, in the countyfof New York and State of New York, have in- .vented certain new and useful Improvements in Varnishes; and I do: hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same.

n This invention relates to varnishes for general uses, and especially adapted for furniture, pianos, etc., and-has for its object to produce a varnish which will be trans arent, will possess ahiglrpolish, will be a solutely Water and moisture resisting, will also bevery highly resistant toward heat, will be insoluble in chemicals in eneral, and will therefore be mord eflicient in use than those heretofore proposed.

To these ends the invention consists in a novel varnish made from a. novel gum, more fully hereinafter disclosed and particularly pointed out in the claims. I

' Inorder that the invention may be more clearly understood, it is said :-.In my prior,

application #702,046, filed .June- 6, 1912,

' entitled artificial gums and process of producing the same, I have disclosed and claimed a new gum and method of making it, which method, when briefly stated, consists in forming a product from a mixture of acetone and phenol to which is added a small qpantitybf acid, in order toproduce what odorous, insoluble in w'at'er,--is relatively- [strong and tenacious, and "it maybe colored with dyes, or with other substances. The

gum produced as above is also soluble in alcohol,"ether, acetone, glacial acetic acld,

' amyl alcohol, amyfh acetate\ and acetylene tetra-chlorid, or mixtures of them.- It is,

' j however, insoluble in oils, such as linseed oil, turpentine, and 'mineraloils. I. find further that this new'gum when first produced is .more or lessv soluble in alkali, that it becomes less and less soluble at say 100,

until when it has been kept at that tempegzli ture for say two hours it is scarcely so that when the gum is dissolved, in one of toluene and alcohol, according to the elieve to be dioxy diphenyl dimethyl. methane. This product is then further acted upon,- as stated in said application above, by-

. Specification, of'Letters Patent. 'Pat nted Oc t. 13, 1914. Application flled January 3, 1913 Ser1a1.No.740,075.

to this condition, however, acids will convert it at ordinary temperatures into a mass which is insoluble in alkali. I have further found the solvents disclosed above, if sufiicient acid is added 'to give it an acid reaction, the varnish produced will harden at ordinary temper-atures into an insoluble mass the'same as if it had been heated to the temperaturesmentioned. I have also further found that the more acid thevarnish is renderd,.the

[quicker will it dry. When in its insoluble condition, it/. is an inodorous transparent mass, quite strong, non-brittle and tenacious.

.It is also-very hard, and will not burn. unless kept continually in a flame. ,In this con.- -dition ofv the gum, I have not found any solvent for it. The above properties are also ,possessed by the varnish to be disclosed below, when in its ,dried condition. Accordingly, in making my varnish out of this gum,

I preferabl dissolve the same in a suitable solvent to t e pro-per consistency, preferring alcohol, or amyl' alcohol, or mlxtures of urpose to-which the-varnish is to be applied. solvent action is, of course, facilitated by gentle heating. I

When the gum is not acid andhas been dissolved to the proper consistency, the varnish is ready for .use, if it is' intended to heat the 'same later in order to render it insoluble. On the other hand, if it is intended to render it insoluble without heating, the gumis acidulated to the proper degree after solution, according to, the celerity with which it is desired to have the varnish dry. The acidulation of the varnish is very useful for a variety of purposes; for instance, when it is to be applied to fine gradesof furniture, or-to other articles which it is either notconvenient, or is injurious to heat.

The i It is an important feature of myinvention 1 that I'am thus enabled to make a varnish which is self-drying at ordinary temperatures,lwhich issubstantially chemically inert to all rea ents, which is insoluble in liquids in generfi, is non-inflammable, possesses a hard surface, and is inodorous. s

It is obvious thatvarious'substances can be mixed with my ,varnish to give it different I properties, or characteristics, such, for example, 'a's coloring matter and dyes, as well as my dioxy diphe' nyl dimethyl methane. And it is fiirther obvious that other compounds may i .be employed to produce mg stated in my-application'a 0v novel gum', as is p e for example, the honfologues of acetone an phenol, such asmethylet l ketone,'-or dieth l ketone, and cresol. if course, when t ese compounds are employed gums which are similar, both chemically'and physically, to the ,Q'ums above employed are produced, and the varnishes made therefrom correspondingly vary-as would be expected by those skilled in thisart.
